If you could be any mythical creature, what would you be and why?

I'm not studied in the language of mythology of any kind, though I have a read a book called The Secret Language of Birds in Mythology, but my limited knowledge likes how Japanese culture keeps mythology alive, and there is one in Japanese mythology which creates the tidal wave after an earthquake called, namazu. Since my favourite author is Japanese, borrows from mythology, and makes absurd stories I'm fine with being a wind up bird now chronicling.
